In this paper concept description of the operating short wall within the bounds of the justified risk approach is described. Analysis of the results of working process modeling are carried out. Engineering-and-economical performance of longwall panels at various values of probability of entry roof fall is studied.
In this paper the methodology for increasing the management efficiency of seals con-struction by using cognitive work analysis is described. The results of cognitive modeling such as a way to reduce labour intensity and seals construction period during the mine rescue oper-ations focused on sealing entries and gob areas are obtained.
